Specification of Letters Patent.

Patented Mar. 2'7, 1917.

Application filed June 16, 1916. Serial No. 104,010.

To all whom it may concern.

Be it known that l, llENRY'MAI-IRER, a citizen of the United States, residing at ll lilnor. in the county of Sargent, State of North Dakota, have invented certain new and useful Improvements in Grain-Separaters; and 1 do hereby declare the following to be a full, clear,- and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to grain separators and has special reference to a grain separator designed particularly for separating the wild oats from a mixture of wild and cultivated oats.

()ne object of the invention is to provide an improved general construction for devices of this character which will efiectively separate the wild from the cultivated oats while at the same time being economical in construction and of few and simple parts so that the device will not readily get out of order.

A second object of the invention is to provide an improved means for feeding different classes of grain to a separator belt so that all of the grain will come in contact with the belt and will enable the belt to pick up the grain belonging to acertain class or classes, arrangement being made to cause such grain to adhere to the belt.

Another object of the invention is to provide means in connection with an inclined endless belt having a fleecy surface whereby the mixture of wild and cultivated oats may be fed across the path of movement of the belt in such manner that all of the wild oats will come in contact with the fieecy surface so that the barbs or beards of the wild oats will engage in the fleece and thus be carried along by the belt.

A further important object of the invention is to provide effective means for separating and disposing of the engaged grain after the same has been taken up by the belt.

Another object is to provide a novel form of scraper for use in connection with a device of this character.

With the above and other objects in View, as will be hereinafter apparent the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and spec1fically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and

Figure 1 is a front elevation of a separator constructed in accordance with this invention;

Fig. 2 is a rear elevation thereof;

Fig. 3 is a side elevation thereof;

Fig. 4iis a section on the line 4l4 of Fig. 1;

Fig. 5 is an enlarged detail view taken in section through the grain feeding spout and showing its relation to the belt.

In the embodiment of the invention herein illustrated there is disclosed a main frame consisting of a pair of side members 10 which are held in fixed spaced relation by suitable bolts or spreaders 11. Pivoted at 12 to this main frame is a pair of struts or legs 10 and these legs are connected at their lower ends to the side members by adjusting bolts lat so that the bottoms of the legs may be drawn closer to or allowed to move farther away from the bottoms of the side members whereby the inclination of the side members to the horizontal may be varied.

In the side members are formed oppositely disposed slots, the slots at the top being indicated at 15 while the slots at the bottom are indicated at 16. An operating pulley or roller 17 is provided and this pulley has journals 18 which fit in the slots 15 and are supported in said slots on bearings'19 which rest on springs 20 held in the bottoms of the slots. Attached to this operating pulley is a crank or belt pulley handle 21 so that the pulley may be revolved. A similar pulley 22 provided with journals 23 is mounted in the slots 16. Trained over the pulleys 17 and 22 is a belt which preferably is provided with a canvas or other like body for the purpose of giving strength and wearing qualities and has a fieecy surface, the body being indicated at 2-4 and the surface at 25. This belt is of such length that the springs 20 are compressed somewhat when the belt is in position and thus the springs tend to hold the belt at all times taut. EX- tending between the side members 10 and in contact with the under surface of the upper flight of the belt is a platen 26 which provents sagging of this upper surface.

At 27 is a hopper and this hopper is preferably fixed to one of the side members 10 at a convenient height to receive the grain before separation. Leading diagonally livery spout indicated in general at 28. This spout is provided with an open side and the remaining side of the spout is preferably made of tin. The bottom of the spout is preferably made of wood and is so formed as to be inclined to the surface of the belt so that grain passing down the spout will be thrown toward the surface. This bottom is at all times in contactwith the surface of the belt and thus the mixed wild and cultivated oats will all be fed diagonally across the upper flight of the belt. By this arrangement the barbs or beards on the wild oats will engage the fleecy surface of the belt and adhere thereto so that as the upper flight of the belt moves upward the wild oats will be separated from the cultivated oats. The cultivated oats will then pass downward along the spout and be delivered from the lower end thereof while the wild oats will be carried over the top pulley or roller and pass downward on the lower or rear flight of the belt.

p F or the purpose of detaching or separating these wild oats from the belt there is provided a scraper and this scraper is of novel form. This scraper consists of a metallic plate having an end at right angles to the side. This end forms a scraping edge 29 while the sides 30 are secured to the legs13 and extend downward along said legs. The bottom end of the scraper is out off diagonally and this end is bent backward toward the body of the scraper so as to form a diagonally extending delivery trough 31. By this means when the wild oats are passed downward on the rear or bottom flight of the belt the edge 29 detaches them from the belt and they drop down the plates to the delivery spout 31 from whence theypass 'oif the bottom of this spout to a suitable receptacle.

It will thus be seen that by the above construction wildand cultivated oats may be readily separated, th one from the other, and that the device will be efiica'cious as all of the cats will be treated.

There has thus been provided a simple and eflicient device of the kind described and .for the purpose specified.

of the invention without departing from the Copies of this patent may be obtained for material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described but it is wished to include all such as properly come within the scope claimed.

lVhat is claimed is:

1. In a device for separating grain, an endless belt having a surface to which a certain portion of the grain will adhere, pulleys supporting the belt, a driving device for one of the pulleys, an open sided feed spout extending diagonally across the front of the belt with the open side facing the belt and the bottom in contact therewith, and means to remove the adherent grain from the belt arranged in spaced relation to the feed spout.

2. In a device for separating grain, an endless belt having a surface to which a certain portion of the grain will adhere, said belt being arranged at an angle to the horizontal, a feed spout extending diagonally downward across the upper flight of the belt, said spout having the side next the belt open and having its bottom in contact with the belt and at an angle across the belt surface.

3. In a device for separating grain, an endless belt having a surface to which a certain portion of the grain will adhere, said belt being arranged at an angle to the horizontal, a feed spout extending diagonally downward across the upper flight of the belt, said spout having the side next the belt open and having its bottom in contact with the belt and at an angle across the belt surface, and means beneath the upper flight of the belt arranged to hold the belt in engagement with the spout.

at. A scraper element for grain separators employing a belt, comprising a plate of metal having one end and the sides at right angles to each other, said end being adapted for engagement with the belt to scrape grain therefrom, the lower end of said plate being diagonally disposed with respect to the sides and being bent back toward the body of the plate to form a trough.

In testimony whereof, I atiix my signature in the presence of two witnesses.
